Monothelitism was the teaching that Jesus had both human and Divine natures but only one Divine will. This is in opposition to the Catholic position that Jesus had both human and Divine wills. Monothelitism had been a thorn in the Church’s side for nearly two hundred years. The last one hundred years had seen it nearly cause a schism between the western and eastern Churches. Enough was enough. Constantinople emperor Constantine IV wanted Christian unity on the issue and wrote a letter to Rome asking for an olive branch. The letter was originally addressed to Pope Donus,] but with mail being what it was thirteen hundred years ago,he was dead by the time it reached him. The new Pope,Agatho,was sympathetic to the emperor and both now worked together to help bridge the two Churches. The Third Council of Constantinople was called and after months of debates and meetings,Monothelitism was finally officially condemned as heresy and all of its followers were condemned as well…….including earlier Pope Honorius. Although he never proclaimed it,he never objected to it,so this got him thrown under the heretical bus with the others. The Council had healed the schism and also confirmed that Rome would officially be home to the one true faith. This was incredible news and I’m sure Pope Agatho would’ve been overjoyed but he was dead by the time word got to him. Again with the slow mail service!!! Anyways,for his work in bringing the two Churches together,Pope Agatho is venerated as a Saint in both Roman Catholic and Eastern Orthodox faiths. His feast day is celebrated on January 10th.
